연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A fuel tank for a vehicle comprising: a tank body; anda fuel supply port device, comprising: a fuel supply port provided at an upper wall of the tank body;a flame arrester extending downwardly from the fuel supply port, so as to permit a fuel to flow into the tank body and for discharging air present in the tank body, the flame arrester having a sidewall and a bottom wall extending radially inwardly from an inner surface of the sidewall;an insertion hole formed in the bottom wall of the flame arrester through which an inside of the fuel supply port device and an inside of the tank body communicate with each other and through which a tool for extracting the fuel can be inserted;an open-close lid for opening and closing the insertion hole; anda gun stopper having a first end connected to a first portion of the sidewall of the flame arrester and a second end connected to a second portion of the sidewall of the flame arrester, the first portion of the sidewall facing the second portion of the sidewall,wherein a first opening is formed between a first side of the gun stopper and the sidewall of the flame arrester and a second opening is formed between a second side of the gun stopper and the sidewall of the flame arrester, andwherein the gun stopper extends continuously between the first end and the second end. 2. The fuel tank for a vehicle according to claim 1, wherein the insertion hole and the open-close lid are provided below the gun stopper. 3. The fuel tank for a vehicle according to claim 2, wherein at least a part of the insertion hole is provided at a position to avoid the gun stopper, as viewed in the axial direction of the fuel supply port. 4. The fuel tank for a vehicle according to claim 1, wherein at least a part of the insertion hole is provided at a position to overlap with the fuel supply port, as viewed in the axial direction of the fuel supply port. 5. The fuel tank for a vehicle according to claim 1, wherein the open-close lid is normally biased by an elastic member in a direction for closing the insertion hole. 6. The fuel tank for a vehicle according to claim 1, wherein the insertion hole is a screw hole, and the open-close lid is a screw member to be screw-engaged with the insertion hole. 7. The fuel tank for a vehicle according to claim 1, wherein the open-close lid is provided with a screw part, and the open-close lid is opened and closed by changing a screw engagement position of an adjusting screw member screw-engaged with the screw part. 8. The fuel tank for a vehicle according to claim 1, wherein the flame arrester comprises: a peripheral wall part formed in a cylindrical shape so as to surround the gun stopper over the whole circumference of the gun stopper;a cap member for covering a lower opening of the peripheral wall part; andcommunication holes, which are smaller in diameter than the insertion hole and which permit the fuel to flow from the inside of the fuel supply port device into the inside of the tank body, are provided in the peripheral wall part and the cap member. 9. The fuel tank for a vehicle according to claim 8, wherein the insertion hole is the lower opening of the peripheral wall part, and the open-close lid is at least a part of the cap member. 10. A fuel supply port device for a fuel tank for a vehicle, the fuel tank including a tank body, a tank cap, and a flame arrester, said fuel supply port device comprising: a sidewall;a bottom wall extending radially inwardly from an inner surface of the sidewall;a fuel supply port provided at an upper wall of the tank body and a top of the sidewall;a gun stopper having a first end connected to a first portion of the sidewall of the flame arrester and a second end connected to a second portion of the sidewall of the flame arrester, the first portion of the sidewall facing the second portion of the sidewall;a first opening formed between a first side of the gun stopper and the sidewall of the flame arrester and a second opening formed between a second side of the gun stopper and the sidewall of the flame arrester; andan insertion hole in the bottom wall through which an inside of the fuel supply port device and an inside of the tank body communicate with each other and through which a tool for extracting the fuel can be inserted,wherein a diameter of the insertion hole is less than half a diameter of the fuel supply port, andwherein the gun stopper extends continuously between the first end and the second end. 11.
